UNITE STATES PATENT OFFICEQ' SAMUEL F. CLOUSER, OF BROOKLYN, NElV YORICRAILWAY SIGNAL APPARATUS.

SPECIFICATION forming part of Letters Patent No. 693,376, dated February18, 1902.

Application filed March 23, 1899. Renewed July 19, 1901 SerialNo.'68,963. (N o model.)

Y T all whom it may concern.-

Be it known that I, SAMUEL F. CLOUSER, a citizen of the United States,residing atBrooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Railway SignalApparatus, of which the following is a full and complete specification,such as will enable those skilled in the art to which it appertains tomake and use the same. I

This invention relates to signal devices for use on railways, andparticularly to that class 1 of signal devices which are designed tosignal to the engineer of a train that he is approaching a drawbridge,defective trestle, or other danger-point.

The invention is fully disclosed in the fol lowing specification, ofwhich the accompanying drawings form a part, in which- Figure 1 is aplan view of a section of a railway-track and turn-table, showing myimproved signal apparatus applied thereto, part of the constructionbeing shown in section; Fig. 2,a side view thereof, part of theconstruction being in sectionj In the drawings forming part of thisspecification the separate parts of my improvement are designated bynumerals .of refer ence, and in said drawings, reference being made toFigs. land 2, I have shown at 5 the rails of a railway-track and at 6the rails of a drawbridge, the frame of which is shown at 7, and in .thepractice of my invention I secure or place at a predetermineddistancefrom the drawbridge and adjacent to one of 4 the rails of the track abox or casing 8, in

which is pivoted a lever or.supp0rt 9, provided at one end with anangular army 10, which is provided at its end with a support 11 for atorpedo or other explosive signal device. At equal distances from thepivoted support 12 of the lever 9 is pivoted to said lever, as shown at13, a rod 14, and the rods 14 pass through tubes 15, which extend alongthe track, as shown in Fig. 1, and adjacent to thedrawbridgeis pivotedanother lever 16,- with the opposite ends of which the rods 14: arepivotally connected, as shown at 17. The

lever 16 is provided with an arm 18, having a vertically-arranged pin19, and secured to the drawbridge or to the side of one of the rails 6thereof is a bracket 20, provided with track to support .a torpedothereover, and said operation will be readily understood from.

the foregoing description when taken in connection with the accompanyingdrawings and the following statement thereof. When the drawbridge is inthe position shown in Fig.

1, there is no danger to an approaching train,

and the train will pass thereover in the usual manner; but if at anytime the drawbridge be turned, it being understood that this operationis performed in the direction of the arrow shown in Fig. 1, the shortarm 21 of thebracket 20 will strike the pin 19 of the arm 18 of thelever 16 and will turn said lever into the position shown in dottedlines in Fig. 1. This operation will also throw the lever 9 intothe'position shown in dotted lines, and the torpedo-support 11 will bedirectly over the adjacent rail 5., As the train approaches the torpedois exploded by the wheels of the engine, and the engineer is thussignaled to the effect that the drawbridge is open, as shown in dottedlines in Fig. 1. When the'drawbridge is moved back into the positionshown in full lines in Fig. 1, the pin 19 is struck by the arm 22 of thebracket 20,

and the operation of the signal apparatus is reversed, thetorpedo-support being moved backwardly and away from its position overthe adjacent rail 5, as shown'in full lines in said figure. It will beunderstood that a torpedo may be placed on, connected'with, or

passes through a' bracket-arm 24, securedtoa block 25, and the adjacentsleeper 26, and

the said lever is mounted between said bracket-arm and said sleeper;butany suitable means for supporting said lever may be employed. 1

My improvement is simple and operation and well adapted to accom ICU inconstruction plish the result for which it is intended, and it will beapparent that changes in and modifications of the construction describedmay be made without departing from the spirit of my invention orsacrificing its advantages.

Having fully described my invention, I claim as new and desire to secureby Letters Patent- 1. A railway signal apparatus adapted to be operatedby a movable portion of the track: mounted on a pivotal support andadapted to turn in a horizontal plane, comprising a support pivotedadjacent to the track at a predetermined distance from said movableportion thereof, said support comprising a lever, one end of which isadapted to be thrown over the adjacent rail of the track, another leverpivotally supported adjacent to the movable portion of the track, saidlevers being in operative connection at each side of their pivotalsupports, and an operating device connected with the movable portion ofthe track, and provided with two arms or projections, one of which islonger than the other, said arms or projections being adapted to turnsaid last-named lever in both directions, substantially as shown anddescribed.

2. A railway signal apparatus adapted for use in connection with amovable portion of a track and consisting of a casing arranged adjacenta fixed portion of a track, a lever mounted therein and having one endportion capable of oscillation into a position above said fixed trackportion, another lever mounted adjacent said movable track portion andprovided with a projecting arm, both of said levers being operativelysupported approximately centrally, and the ends of each lever beingconnected operatively with the ends of the other lever, said movabletrack portion being provided with a bracket secured to one of the railsthereof and provided with a shorter arm which approximately parallelssaid rail, and a longer arm at an angle there with, which bracketoperates in connection with a pin fixed to the arm of said lever whichis mounted adjacent said movable track portion, to swing said last-namedlever in both directions whereby a torpedo placed upon one end of saidlever adjacent the fixed portion of said track, may be swung above andretracted from said fixed track portion, substantially as shown anddescribed.

3. In a railway signal apparatus adapted for use in connection with amovable portion of a track, and comprising a first pivoted membermounted adjacent a fixed portion of a track, and adapted to hold atorpedo and to throw the same over said track portion, and a secondpivoted member operatively con- -nected therewith, and mounted adjacentsaid movable track portion and provided with a pin or stud; a bracketsecured to one of the rails of said movable track portion and providedwith ashort arm which approximately parallels the adjacent track andwith a long arm which projects at an angle thereto, said pin orstudbeing arranged to operate in connection with and between said arms, andto be moved thereby to pivotally move said first member, substantiallyas shown and described. In testimony that I claim the foregoing as myinvention I have signed my name, in presence of the subscribingWitnesses, this 22d day of March, 189.).
